Be it knownthet I, HORACE citizen of the United Statemresiding zit-New York, in'the e my of Kings end'State of New York-, hevejiiwented certain new and nseful'lm' rove' nentsinzTelgmphio Transmitters, 0 Whichihefollowing is e specificatio'n, reference being hed'to the drawings eocompsnying and forming part of the set-me.

Inv my prior tent; No. 767,303, dated August-9,1904, have described and claimed a telegraphic transmitt'ex, the essential festures'of which are it key, a vibrator, and suiteble electrical connections, by means oi which the movemento'f the key in one dire- 0 itionclo'see the circuit continuously to the l' ine', ivhile a movement of the key in the o'pthe spaces ancldashes are thus determined, dr-

jiosit'e direction closes the line circuit through thefvlbretei';which ogemtes to send a; sue

cession 10f. impulses-es long as the key remains in sllclipo'sition. 1 The first movement of the keyisused to send dashes While the. second movement sends dots. The lengths-0f of dots, whichcontinile to lee-sent as 1011;; as

' the key isheld in the proper position; but the length of the impulses which produce i the Iglots and theii rztpldityefe cletei minecl hy'the edjustmentor regulation of the period of vi j bratio'n of .the"vibreto1i. The transmitter, just described lessens the number je f meme movements requirediln Morse sending,

hence greatly feduces the leborinvolvecl.
